Abstract

The invention relates to a water-repellent, oil-repellent, sun-proof, anti-bend torsion and cold-resistant matt-leather-membrane aqueous coating adhesive for textiles and a preparation method of the matt-leather-membrane aqueous coating adhesive. The preparation method comprises the steps of emulsifying isooctyl acrylate, isobornyl methacrylate, glycidyl methacrylate, trifluoroethyl methacrylate, vinyl trimethoxysilane, hydroxypropyl acrylate, fatty alcohol ethoxylate XL90 and dodecyl benzene sulfonate to trigger polymerization, and compounding a thickening agent, namely an associated polyurethane flatting rheological agent, a cross-linking agent, namely terminated isocyanate, a flatting agent, namely polymethyl urea resin and silicon dioxide with the particle size of 2-7 microns, so as to obtain the matt-leather-membrane aqueous coating adhesive.

Description

technical field [0001] The invention relates to a water-based coating glue for matte film, which is a modified acrylic resin polymer, which is used for coating chemical fiber, pure cotton or chemical fiber and pure cotton blended fabrics, so that the fabric can achieve the effect of imitation leather. Moreover, the film has the characteristics of water repellency, oil repellency, sun resistance, twist resistance, cold resistance, soft hand feeling, and strong washing fastness. Background technique [0002] In recent years, with the improvement of living standards, consumers prefer products with both functionality and style. Water-based coating fabrics with matte film and traditional Compared with matte film fabrics, it is more functional and more environmentally friendly, which greatly improves the added value of the product. [0003] At present, there is no technical disclosure of a multi-functional matte film water-based coating adhesive with water repellency, oil repelle...
